Convert torr to millimeter water (4°C)
Please provide values below to convert torr [Torr] to millimeter water (4°C) [mmH2O], or Convert millimeter water (4°C) to torr.
1 Torr = 13.5954723354 mmH2O. To convert torr to millimeter water (4°C), multiply the value by 13.5954723354; to go the other way, divide by it (1 mmH2O = 0.0735538990727 Torr). Both units measure pressure and appear in everyday as well as technical calculations, so switching between them quickly is often useful.

Torr
The torr is a unit of pressure defined as 1 millimeter of mercury (mmHg) at standard gravity and temperature, approximately equal to 133.322 pascals.
History/Origin
The torr was introduced by Evangelista Torricelli in 1644, based on his experiments with mercury barometers, as a unit to measure atmospheric pressure. It was historically used in meteorology and physics before the adoption of the pascal.
Current Use
Today, the torr is primarily used in fields like vacuum technology, physics, and medicine (e.g., blood pressure measurements), although it has largely been replaced by the pascal in most scientific contexts.
Millimeter Water (4°c)
Millimeter water (4°C) is a unit of pressure measuring the height of a water column at 4 degrees Celsius that exerts a specific pressure.
History/Origin
The unit originated from the use of water columns to measure pressure, particularly in hydrology and medical applications, with standardization based on the density of water at 4°C.
Current Use
It is primarily used in medical and scientific contexts to measure low pressures, such as intracranial pressure, respiratory pressures, and in calibration of pressure sensors.
